USPTO Patents Application 10695178

IN THE CLAIMS:

Please amend the claims to read as follows:
Claims 1 to 28 (Canceled).

29. (Withdrawn) A method of releasably attaching a hub to a catheter, wherein the hub
comprises two hingedly connected opposing portions, each portion having an inner face, at
least one channel to accommodate at least one lumen of a catheter disposed on the inner face
of at least one of the two hingedly connected opposing portions, and a means for releasably
locking the opposing portions in the closed position; the method comprising:

(a) placing the at least one lumen of a catheter in the at least one channel of at
least one of the two hingedly connected opposing portions;

(b) folding the other of the two hingedly connected opposing portions over the
at least one lumen thereby mating the inner face of one of the two hingedly
connected opposing portions with the inner face of the other of the two
hingedly connected opposing portions and fitting the two hingedly
connecting portions around the at least one lumen; and

(c) releasably locking the hub in the closed position.

30. (Withdrawn) The method according to claim 29, further comprising longitudinally
translating the hub along the proximal end regions of the first and second catheters.

3 1 . (Withdrawn) The method according to claim 29, further comprising juxtaposing the first
lumen against the second lumen in a distal end of the hub and separating the first and second
lumens in a proximal end of the hub.

32. (Withdrawn) The method according to claim 29, further comprising releasably
connecting the hub to a patient.

33. (Withdrawn) The method according to claim 29, further comprising removing the hub
from the catheter by:

(a) unlocking the hub;

(b) unfolding the two hingedly connected opposing portions; and
sliding the hub away from the catheter.

34. (Currently amended) A multiple catheter assembly, comprising:

a first catheter having a first distal end region and a first proximal end region joined
by a first intermediate section;

a second catheter having a second distal end region and a second proximal end region
joined by a second intermediate section;

first and second extension tube assemblies having first and second distal end portions
respectively associated with the first and second proximal end regions of the first and second
catheters; and

a_ an initially separate hub member adapted to be releasably attachable to and around
the first and second proximal end regions of the first and second catheters distally of the
proximal ends thereof, such that portions of the proximal end portions extend through the
-5-

hub member and proximally beyond the proximal end thereof to be connected to respective
medical devices.

35. (Previously presented) The multiple catheter assembly of claim 34, wherein the cross-
sectional shapes of the first and second proximal end regions is circular, and the cross-
sectional shapes of the first and second distal end portions of the first and second extension
tubes is circular.

36. (Previously presented) The multiple catheter assembly of claim 35, wherein the cross-
sectional shapes of the first and second intermediate sections of the first and second catheters
is semicircular, and the first and second catheters have transition sections between the
circular cross-sectional shapes of the first and second proximal and distal end regions and the
semicircular cross-sectional shapes of the first and second intermediate sections.

37. (Previously presented) The multiple catheter assembly of claim 36, wherein the first and
second intermediate sections of the first and second catheters are splittably joined to each
other.

38. (Previously presented) The multiple catheter assembly of claim 37, wherein the first and
second intermediate sections of the first and second catheters are splittably joined to each
other by adhesive.
